SPECIFICATION forming part of Letters Patent N 0. 738,183, dated September 8, 1903.

Application filed September 13, 1902. Serial No. 123,231: (1% model.)

To all whom 256 may concern-.-

Be it known that I, OLIVER F. GOOD,a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in a Combined Gas or Vapor Generator and Motor; and I do declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to a combined gas or vapor generator and motor.

The object of the invention is to provide a combined gas or vapor generator and motor in which the heat or power generated is produced within a comparatively short time. The heat obtained for generating the power after the working stroke in the explosivecylinder is admitted from said explosivecylinder directly to the generator. Therefore it has the effect of immediately vaporizing the oil, water, or other element admitted to said generator from the cooling-jackets of the cylinders. This power is introduced from the generator directly to a power-cylinder in a manner similar to the introduction ofsteam from a boiler and may be used for motorpower or for heating purposes.

In the present invention the following instrumentaiities are utilizednamely: An aircompressor; a gas or fuel compressor, both of which furnish air and fuel in proper proportions to an explosive-cylinder which is entirely separate and distinct from either of said air-compressor and gas or fuel compressor, although the said explosive-cylinder may be an integral part of the air-compressor or the gas-compressor, or the entire threenamely, the air-compressor, the gas-com pressor, and the explosive-cylinder-may be one integral casting with the various chainbers separated and united with ports and valves; a pump through which water, oil, or other cooling element is introduced to the compressor cylinder cooling jacket, and from there said water, oil, or other cooling element is introduced to the explosive-cylinder cooling-jacket; a generator having a communication with the explosive-cylinder and through which the heat and force generated back of the piston in said explosivecylinder is introduced to said generator. The interior of said generator is provided with one or more perforated distributing tubes or ports, the purpose of which is to distribute the heat entering said generator throughout the interior thereof to come in contact with the oil, water, or other element to be heated and expanded therein in the quickest possible time and whereby the said water, oil, or other cooling element from the cooling-jackets so introduced to the generator rapidly becomes converted into gas or vapor. The cooling-jacket inclosing the explosive-cylinder communicates with the interior of the generator and admits the oil, Water, orother element in a heated condition to said generator. It will therefore be seen that the Water, oil, or other element usually supplied to the cooling-jackets of compressors and the like for the sole purpose of keeping the same cool is in the present instance utilized for an additional purposenamely, to provide heat or power through the medium of a generator. The prime object of the invention is to admit air and gas in the proper proportions to an explosive-cylinder and after the explosion and expansion of the gases in said cylinder to concentrate in a generator the heat from said explosive-cylinder and the heat from the cooling-jackets of the compressor and the explosive cylinders.

In the present invention the heated elem en ts from the cooling-jackets are not wasted, as heretofore; but they are conveyed to the interior of a generator under high temperature, where the heat from the explosive-cylinder after expansion is also introduced to expand the elements thus introduced to said generator from thejackets of the compressor and explosive cylinders.

Preceding a detail descriptionof my invention, reference is made to the accompanying drawings, of which Figure l is a general plan view showing the apparatus connected up. Fig. 2 is a longitudinal vertical sectional elevation through the explosive-cylinder and the generator on the line a; mof Fig. 1. Fig. 3 is a longitudinal vertical sectional elevation through the com- ICO pressors and engine-cylinders on the line y 1 of Fig. 1. Fig. 4 is an enlarged detail View of a portion of the actuating mechanism of the throttling device for controlling the admission of fuel or gas to the eXplosivecylinder. Fig. 5 is a top plan view of the mechanism shown in Fig. 4. Fig. 6 is an enlarged sectional view of the fuel-admission valves.

Throughout the specification similar reference characters will be found to indicate corresponding parts of the drawings.

Referring to Fig. 1, A and B designate, respectively, the two main portions of the apparatus, the compressor and engine cylinders on one side and the explosion-cylinder and generator on the other side, all of which are connected to a common crank-shaft J. The gas-compressor O and the air-compressor D are arranged in alinement, and the pistons O and D thereofare connected to a common conneciingrod D which, as before stated, is connected to the crank-shaft J. The powercylinder 1, which is fed through pipe H from the generator-chamber G, is also placed in alinement with the gas and air compressors and is connected to the connecting-rod B by means of a cross-head D" and con nectingrods 1 said rods being connected to a yoke I, to which the piston-rod I" of the power-cylinder I is connected. The cross-head D" moves on guides A, located on opposite sides of the frame A. The ends of the rods 1 adjacent to the yoke I move in guides I on opposite sides of the power-cylinder I.

H is a hand-valve of the globe type controlling the pipe H, and c is a slide-rod. attached to a connecting-rod c, which has a reciprocating movement from eccentric c on shaft J. The slide 0 is connected to the stem 0" of a slide-valve which controls the admission through pipe H of the steam from the generator-chamber G to the power-cylinder I.

E is a pump which supplies the several cooling-jackets surrounding the cylinders with the cooling element through pipe at. The said cooling element enters said pump through pipe h. The rod E, which drives the piston E in said pump, is driven from the crankshaft J through eccentric or crank g and connecting-rod g. The cooling element, as be fore stated, leaves the pump E through pipe at and enters the cooling-jacket of the aircompressor D. A communication is made between the cooling-jacket of the air-compressor and the cooling-jacket of the gas-compressor 0 through a pipe I).

e designates a pipe controlled by a valve e and forming a communication from the aircompressor D to the ex plosive-cylinder F, the said pipe having a valve e, which is located in the head of the explosive-cylinder F and opens inwardly under the pressure of air from the air-compressor D. The rear of said compressor-cylinder is open, as indicated at G and thus communicates directly with the generator G. This is an important feature of the construction for many reasons. Any leakage fromthe explosive-cylinder will find its way directly to the generator, and, further, the heat from the piston otherwise lost in an open-end explosive-cylinder is utilized in heating and expanding the products within the generator, and, further, by thus having the explosive-cylinder opening into the generator the pressure in said generator exerts an effect on the back of the piston on the return stroke in compressing a charge, and thereby the crank-shaft is relieved of a certain amount of work. For example, if onehundred pounds pressure to the square inch is carried in the generator G the crank-shaft is relieved to the extent of the pressure exerted upon the piston from the generator in the movement of said piston to compress a charge and the friction of the moving parts is correspondingly reduced. By constructing the cylinder with the end thereof opening into the generator the stuffing-box for the piston-rod K is enabled to be removed a desirable distance from the explosive-cylinder to prevent the damaging efiects due to the heat of said cylinder. The stuffing-box, it will be noted from Fig. 2, is mounted in the upright wall which connects the dome G with the lower wall of the generator.

h designates a gas or fuel supply pipe having valves h and h, which are mounted in suitable parts of the gas-compressor cylinder 0. These valves are opened alternately according to the position of the piston O to admit gas or fuel into said cylinder for compression.

f designates a gas or fuel feed pipe for the explosive-cylinder F. This pipe has an outlet through valve f, which is located at a suitable point in the cylinder 0, and an inlet through a valve f, which is located in the head of the explosive-cylinder F. The valve f" is an ordinary puppet-valve and seats against the case x of a throttling-valve to, which valve acts as a throttling device in the admission of fuel to the valve f The valve f" is actuated by a tappet-rod u, which in turn is actuated through a connecting-rod said connecting-rod being attached to a slide 072, that is operated from an eccentric m on the shaft J by a connecting-rod m. The throttling-valve 11, turns in the case 00, such movement being transmitted to said valve through a connecting-rod O and bell-crank lever 0 The valve to has a port 14 whichin the movement of said valve is broughtin and out of a position to communicate with the port M", which communicates with the feed-pipef.

n designates a bell-crank lever which is operated by the governor M. One arm of said lever connects with a yoke O, hereinafter referred to, through a rod nand imparts movement to said yoke according to the speed of ICC the governor. The slide 0 is connected to the bell-crank lever O l by a connecting-rod 0 The governor is connected to the crank-shaft J by a belt I.

It will thus be seen that the throttling-valve '20 (see Fig. 6) obtains its movement from the governor and regulates the feed of gas or fuel through the pipe fto the puppet-valve f. The latter valve, it will be understood, has a movement from'the crank-shaft J through the eccentric m, connecting-rod m, slide at", connecting-rod O, and tappet-rod u. The compressors C and D are preferably two-stage compressors.

Referring to Fig. 3, as the piston D moves away from the crank-shaft air to fill the cylinder is drawn in through valve i. The piston traveling back or toward the crank-shaft compresses the air, while the opposite end of the cylinder is filled through valve 11 to the point where the piston passes the opening of valve WVhen the piston passes the opening of the valve D valve 6 closes by the compressed air passing around the piston through port a and valve D", said valve opening inwardly. All the air in the forward stroke of the piston is forced around through port a, filling the opposite end of the cylinder under pressure, and is further compressed by the piston in its return movement and is forced into the explosive-cylinder at the proper periods. The gas or fuel is compressed in the same manner and is taken into the explosivecylinder through the throttling device in the manner and at the periods described. The pipe H, forming the communication between the generator and the power'cylinder I, connects with the dome G above the generator.

G is a pipe forming a communication between the cooling-jacket of the explosive-cylinder F and the lower portion of the generator, as shown in Fig. 2.

q designates a series of ports in the explosive-cylinder communicating with duct g, which in turn'communicates with a series of one or more distributing-pipes Q, located in the lower portion of the generator and having their lower surfaces provided with a suitable number of perforations through which the heat and force from the explosive-cylinder F is distributed throughout the interior of said generator.

The cooling element from the cooling-jackets, as before stated, enters the generator through the pipe G in proximity to the distributing-pipes Q. The consequence is the heat rapidly vaporizes and expands the oil, water, or other element within the generator, from whence said vapor is conducted to the power-cylinder I, as before stated. The eX- plosive-cylinder F is open at its inner end and communicates with the interior G of the generator. The piston K of the explosivecylinder in its back stroke compresses the air which said cylinder receives from compressor D. After the compression of said air is completed or is about completed the gas or fuel is admitted to said cylinder from compressor O and is exploded, driving the piston outwardly or toward the open end. As soon as the piston uncovers the ports 1 the products of combustion enter and are forced into the generator-chamber through said ports q and the duct q. The air from the compressor-cylinder coming into the explosivecylinder at a high state of compression Will force said products of combustion out of said explosive-cylinder into the generator-chamber and will cause said explosive-cylinder to fill with a fresh charge of air after each explosion.- The air entering the explosive-cyl inder from the compressor D is under a high state of compression, and the further compression of said air by the piston within said explosive-cylinder imparts to the air such a high temperature that the gas or fuel is ignited thereby as soon as said fuel is admitted to the cylinder. The piston K is connected to a piston-rod K, which is attached to the sliding cross-head B which in turn is connected to the crank-shaft J by connectingrod B. The said cross-head moves in guides B B located on opposite sides of the frame B. The slide m is mounted on a support m secured to the explosive-cylinder, and is given a constant movement from the eccentric on through the connecting-rod m. On one side of said slide there are secured two oppositely-pointing projections 0 O is a yoke pivoted at O to theslide O on support m This yoke O has a pivotal connection at p to the rod or, which, as before stated, is given movement according to the speed of the governor. The project-ing arms 0 O of the yoke 0 project on lines obliquely to the shank of the yoke and are provided on their inner surfaces with serrations or teeth. When the speed of the governor is such that it actuates the rod 71, there will be a tendency to move the yoke on its pivot 0'. If such movement occurs when the slide m is moving to the right, as shown in Fig. 4:, the yoke and the slide 0 will be moved together by the slide m". The right-hand projection 0 it Will be seen, engages the arm 0 on that side, and thus prevents the yoke from turning on the pivot 0''. If the governor through the connecting-rod u moves the shank of the yoke to the left in Fig. 4, the projection O on the left side of the slide m" will engage the adjacent arm 0 and will impart a movement of the slide 0 to the left, as seen in Fig. at. The throttling-valved will be thus opened and closed. According to the position of the slide m and the yoke O, as shown in Fig. 4, the said throttling-valve u is halfway opened. The power or heat concentrated in the generator may be utilized through the power-cylinder I for motive-power purposes. When so utilized, power is transmitted to the cross-head D" through connecting-rods I I and thence either to the compressors C and D or the crank-shaft J. When used for heating purposes, the power-cylinder I is discon- FOO nected, and pipe H is connected to distributing-pipes.

Having described my invention, I claim 1. In a combined gas or vapor generator and motor,a generator, a water-jacketed explosivecylinder having an end thereof opening into said generator, ports and ducts forming an exterior communication between said explosive-cylinder and said generator, said ports and ducts being controlled by the piston Within the explosive-cylinder, and a communication between the water-jacket of the cylinder and the interior of the generator, substantially as and for the purposes specified.
